Re: [Python-Dev] Is it useful to update cgitb module?
Extremely useful … for CGI scripts. Now, my sample size is quite small – mainly the #python irc channel on freenode, but I have been informally asking for a few years, and you are the first person I have encountered who admitted to writing and maintaining new CGI based sites. I still say the value of supporting such an obsolete model is… questionable. That said, I have no power to block commits.

In both text and html versions: When a module is called, there are no parameters (displayed as '()'). I think they are unnecessary. Perhaps the parentheses should be removed? Perhaps it's better to keep them for backward compatibility? ### example for the text version ### $ python3 demo.py [...] /home/stephane/src/cgitest/demo.py in () 7 def func1(a, b): [...] ### end of example ### 2. In html version only: a. If the executed code is in : in this case, it is not shown in the html version because the square brackets are interpreted as a html tag (see the picture in attachement). b. Update the style of the html or/and using html5. It would be prettier but it will be a big change for probably too few benefits. What do you think about them? I can report bugs and send pull-requests for them but I would prefer to get feedbacks before. 2a is definitely a bug. Please open an issue on the bug tracker for. 1 can be considered as a bug or as a request for enhancement. Needed to look at the code closer. And 2b is a separate request for enhancement.

I thought it is a misconfiguration on my computer. It's not your computer, it's the test suite. It uses the old asyncore library. The test has become unstable since the ssl module properly checks host names, see https://bugs.python.org/issue32706 and https://bugs.python.org/issue32753. In Python 3.6 and earlier, a hostname verification error resulted in a closed connection. Starting with Python 3.7, the ssl module checks the hostname earlier in the TLS handshake. A verification error results in a TLS handshake alert and an exception on the server side. Sometimes the old server code in asyncore runs into a race condition and the test fails. The whole test framework needs to be rewritten from scratch and replaced with something better. I haven't had time to work on it.

In addition to the "magic" support triggered by 'cgitb.enable()', the
module also exposes useful utility functions ('cgitb.html()' and
'cgitb.text()') which are used by non-CGI third-party libraries to render
tracebacks for debugging purposes. Enhancing those methods seems pretty
reasonable to me.

Re: [Python-Dev] Is it useful to update cgitb module?
cgitb is useful even outside of cgi scripts. I've used "cgitb.enable(format='text')" in the several scripts to get "better" exceptions.

Re: [Python-Dev] Are undocumented functions part of the stable ABI?
On 2018-04-08 05:17, Nick Coghlan wrote: Changing macro definitions doesn't break the stable ABI, as long as the *old* macro expansions still do the right thing. To me, it looks like a bad idea to change macros. Imagine that the PyCFunction_Check macro changes in Python 3.8. Then an extension module compiled on 3.7 (but run on 3.8) would behave differently from the same extension compiled on 3.8. I cannot imagine that this is in line with the "stable ABI" philosophy.
